Federal prosecutors said five people pleaded guilty this week to roles in a multi-state drug trafficking organization operating in Huntington. The five are the last of 18 people indicted to enter guilty pleas in the case, the result of a long-term investigation in which law enforcement seized more than 47 pounds of fentanyl, 4.5 pounds of cocaine, 2 pounds of heroin, 14 firearms and $335,000, according to a news release from the U.S. Attorney’s Office for the Southern District of West Virginia. 28-year old Dillon Young of Sissionville was among those who pleaded guilty, along with three people from Huntington and one from Ohio. They’ll be sentenced this summer.
